Summary
This study explored the daily challenges faced by individuals with phakic presbyopia, revealing significant impacts on near vision functioning and daily activities. Findings inform new assessments for vision correction and near vision capabilities.
Area of Science:
- Ophthalmology
- Vision Science
- Patient-Reported Outcomes
Background:
- Presbyopia is the age-related loss of near focusing ability, impacting daily life.
- This study focused on the lived experience of phakic presbyopia (presbyopia in individuals with natural lenses).
Purpose of the Study:
- To understand the lived experience of phakic presbyopia.
- To identify visual function symptoms and their impact on daily activities.
Main Methods:
- Qualitative concept elicitation interviews were conducted with 50 individuals with phakic presbyopia and 7 healthcare professionals.
- Thematic analysis was used to analyze verbatim interview transcripts.
Main Results:
- Key symptoms included impaired near visual acuity (100%), difficulty in dim light (84%), and eye strain (74%).
- Functional impacts involved difficulties with reading (98%), near vision tasks (96%), and daily activities like smartphone use (98%).
- Emotional, work, financial, and social impacts were also reported.
Conclusions:
- The findings provide a comprehensive understanding of the phakic presbyopia experience.
- This informed the development of a conceptual model and patient-reported outcome assessments.
- The study sample excluded individuals with uncorrectable vision issues.

01:22Photoreceptors and Visual Pathways
6.8K
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category,...

01:16Focusing of Light in the Eye
3.5K
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

01:17Accessory Structures of the Eye
2.1K
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

01:25Glaucoma: Overview
961
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...

01:12Visual Agnosia
451
Visual agnosia is a condition characterized by the inability to recognize visually presented objects despite having normal vision. For instance, a person with visual agnosia can describe the shape and color of an object but cannot identify or name it. This impairment does not affect their visual field, acuity, color vision, brightness discrimination, language, or memory. An example of this condition in a social setting is someone at a dinner party asking for "that silver thing with a round...

01:20Anatomy of the Eyeball
7.8K
The eye is a spherical, hollow structure composed of three tissue layers. The outer layer — the fibrous tunic, comprises the sclera — a white structure — and the cornea, which is transparent. The sclera encompasses some of the ocular surface, most of which is not visible. However, the 'white of the eye' is distinctively visible in humans compared to other species. The cornea, a clear covering at the front of the eye, enables light penetration. The eye's middle...
